LAM P-STCVE- SPECIFICATION forming part of Letters Patent No. 367,256, dated July 26, 1857.

Application filed September 8, 1886. Serial No. 213,045. (No model.)

T all whom it may. concern:

Be it known that I, CLARK S. WEST, of Boston, in the county of Suffolk and State of Massachusettshave invented certain Improve ments in Oil-Stoves, of which the following is a full, clea and exact description, reference being bad to the accompanying drawings,making part of this specification, in which-- Figure 1 is a perspective view of an oil-reservoir and a water-tank belonging to an oilstove of the class to which my present improvements are to be applied, Fig. 2, a view of my improvedcasing detached; Fig. 3, a view of a chimney-holder constructed in accordancewith this invention; Fig.4, avertical section through I the center of the aforesaid elements assembled in position. Fig. 5 is a view ofthe oil-reservoir detached, Fig. 6, a view of the water-tank inverted. Fig. 7is a detail view of the fastening-rod.

The aim of my present invention is to perfect the constructionof oil-stoves and thereby derive the maximum efficiency therefrom; and

thisinvention consists in certainimprovements in the draft-passages by which the currents of claimed.

In the said drawings, A represents a rectangular oil-reservoir having a flat bottom, on which it rests. p

a is an inlet-orifice, through which the liquid fuel is supplied.

b is ascrewtap for closing the inlet-orifice. In the center of the top of the oil-reservoir is formed a large rectangular opening or well, B, surrounded on all sides bya rectangular-flange or wall, 0 c',whieh projects both above and below the top of the reservoir, the size of the well B being adapted to snugly receive the rectangular flanged .wall G,extendingjdown from the closed bottom of the water-tank D, whereby 'no lateral play or loss of motion occurs between them, the oil-reservoir being provided with four short standards, d, rising fromits corners,

upon which the bottom of the water-tank rests.

' To fasten the oil-reservoir and, water-tank together, I provide the interior ofthe wall 0 with a tube, 8, extending horizontally across it and the oil-reservoir Wall 0, with circular holes 9 in linetherewith for the reception ofa long fastening-rod, 10, Fig. 7, by which,when withdrawn, the water-tank may be instantly removed from the top of the oil-reservoir, should it be desired to obtain access to the wick, in case it is accidentally lowered, or in cleaning out or examining the interior of the reservoir. Instead of one continuous rod 10 two short ones may be substituted therefor.

The rectangular flange or wall 0', projecting down from and into the oil-reservoir, prevents the swashing of the oil up against the sides of the wick-tubes e'e,which extend down through the water-tank (by water-tight connections) into the oil-reservoir.

11 are ratchet-wheels, and 12 the rods to which they are secured, and by which they are turned to adjust the wicks 13.

Around a portion ,of each of the wick-tubes projecting above the top of the water-tank D is located an upright tubular curb, f, inclosing a space within which, on each side of a wick-tube, is placedastrip, h, of non combustible fibrous materialsuch as asbestus, mineral wool, &c.which extends down to and is supported by the bottom of the water-tank, the said fibrous strip serving as a water or vapor elevator, its top reaching to a point a short distance below the top of the wick-tube. The capillary action of this fibrous elevator h conducts water to a point a little below the base of the flame, and the heat imparted to the wa- 'ter by contact of the fibrous elevator with the wick-tube vaporizes the water,which vapor is mixed with the vapors produced by the flow of the hydrocarburet through the draft-currents impinging on the base of the flame, now to be IOO LII

the external air entering the openings 1 in the sides of the casing passes up through the slots 7; and is directed over the water-elevator to the base of the flame. 'lo still further increase the eflieiency of the stove, I locate a chimneyholder,G,upon the top of the casing F,a longt tudinal opening or slot of the exact size of each wick-tube being formed in its top to allow its being located in position around said tubes. This chimney-holder G is provided with two or three rows of perforations, Z, surrounding each wick-tube opening, and a small space intervenes between the top of the casing and the chimney-holder, by which construction the external air passes through the openings i into the space between thetop of the watertank D and the casing across the tops of the water-elevators l1,- thence upithe slots 7.:in the top of the casing; thence up through the perforations Z in the top of the chimney-holder G to and upon the base of the flame, the aforesaid construction, location, and arrangement of draft-passages insuring the convergence and concentration of the currents of air, which, charged with the vapor from the heated fibrous water-eonduetors l1, mix it with the volatile products of the heated oil as they are drawn up the wicks, thus enriching the carbureted air and affording a steady and brilliant flame, my aforesaid invention also enabling me to effect a great saving in oil.

\Vhere the chimney-holder is perforated throughout its entire top, as heretofore, the currents of air are diverted or dissipated, instead of being concentrated, as is the case when they pass through the perforationsloeated only immediately around the wieletubes, as herein shown and described, in accordance with my present invention, the impinging of the our rents upon the igniting-point and their saturation with the vapor from the water overconr ing any tendency to smoke or flicker, and rendering combustion perfect.

I am aware that it is old in oil-stoves to sun round the wick-tubes with other tubes in which are placed absorbing material communicating with a water-reservoir in order to prevent, by the evaporation of the water so absorbed, heat from passing or being conducted to the oil-receiver; but I believe that I am the first to so construct the various parts of the stove that the aqueous vapors shall be accurately directed into contact with the flame to assist in the combustion of the oil.

I claim- 1. The combination of the oil-reservoir A, removable watertank located thereover, perforated casing F upon the water-tank, having a flat top closed, except as slotted in immediate proximity to the wick-tube, the flat chimney-holding plate G, formed with perforations contiguous to and surrounding the wick-tube, the wick-tube projecting up through said plate G, and the water-conductors h, terminating just below the slot 7.: in the top plate of easing F, substantially as set forth.

2. An oil-reservoir, A, having its top provided with a centrally-loeated well, B, surrounded by an uprightcurb or wall, 0 c, which extends above and below the top, in combination with and for the reception ofadetaeliable water-tank, D, having a wall, 0, depending from its bottom, a wick-tube, a surrounding curb, f, at the top of the tank, anda fastening device, as and for the purposes set forth.

Awater-tank, D, having at its bottom a central eurb or wall, 0, and a tube, 8, extending between two opposite sides thereof, and an oil-reservoir having a central opening or well, B, surrounded by a curb or wall, 0 0, having two of its opposite sides provided with holes 9, in line with the guide-tube S, in combination with a removable fastening-rod, as specifled.

Vitness my hand this 11th day of October, 1885.
